HI C.,
Topically on the eyes is difficult. High grade tea tree oil will get rid of it but NEVER put it near the eyes. The chin would be fine.
Viruses tend to stay away from people that have healthy digestive systems. Kid's L-Lysine will get rid of it. It's an amino acid that is depleted with certain illnesses/stress and needs to be replenished. The virus will go away with particular digestive enzymes as well. I used a product for the chicken pox called Virostop by Enzymatic Therapy. You can ask at the health store and they should be able to help with any particulars for your son.
The natural community has a better handle on viruses than the medical community. Cutting a virus tends to make it spread ( like a fever blister) so removing them, especially around the eyes could be dangerous.
God bless,
M.
